from The Century Dictionary.
- noun In placer-mining, a name sometimes given to gold occurring in exceedingly fine particles.
Sorry, no etymologies found.
In this deposit there was enough flour-gold to enable any good placer miner to make days 'wages by rocking the rich streaks along the bars and banks.
It is often in the form of spangles called float-gold and flour-gold.
As some flour-gold is here found, the cradle-bottom should be cut with cross-grooves to hold mercury; and the latter must be tempered with sodium or other amalgam.
There will not be much loss by float-gold, flour-gold, or paint-gold, the latter thus called because it is so fine as to resemble gilding.
